Changing car brakes?

CAN I CHANGE MY CARS BRAKES BY USING THE JACK THAT CAME WWITH THE CAR TO HOLD ONE SIDE OF THE CAR UP? i WILL ALSO PUT SOME MASON BRICKS(STRONG BRICKS) ALONGSIDE THE JACK SO INCASE THE JACK LOOSES IT, IS THIS OKAY? THANK YOU!!!!!!!!|||sure can!!|||you should be fine, but jack stands would be best.|||Yes, but spending a few pennies on some axle stands is a better idea as bricks, no matter how hard, can crumble if the car slips off the jack. http://www.uktools.com/product_info.php?鈥?/a>
